 环境：Centos6.5

行为：安装nginx

问题：　　

nginx: [emerg] socket() [::]:80 failed (97: Address family not supported by protocol)
nginx: configuration file /etc/nginx/nginx.conf test failed

解决：

   vim /etc/nginx/conf.d/default.conf
将：
    listen       80 default_server;
    listen       [::]:80 default_server;
改为：
    listen       80;
    #listen     [::]:80 default_server;

启动nginx就行了。。
